Delayed seroconversion

Jul 7, 2011

I have a strange question that probably hasn't been asked before: I had given a blood donation (which was recalled before used) a week after my last sexual exposure to someone. I found out info after the donation that made me want to get HIV tested. I had a PCR DNA test at 28 days, and antibody tests at 55, 70, 85, 90 and 97 days.

My question is: would the pint blood donation 7 days last exposure (less red blood cells in my system) slow down the possible HIV virus production or antibody production and thus affect the different tests I had? Would the tests themselves be inaccurate? Thank you for answering.

Hi.

Nope! Blood donation would not alter HIV test accuracy or the duration of the seroconversion window period.
